ELECTROVIBRATORY APPARATUS FOR THERAPEUTICAL PURPOSES.

SPECIFICATION forming part of Letters Patent No. 738,403, dated September 8, 1903.

Application filed January 28, 1903. Serial No. 140,901. (No model.)

To all whom, it may concern..-

Be it known that I, FRED HARVEY BROWN, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented a new and useful Electrovibratory Apparatus for Therapeutical Purposes; and I do declare that the following is a description of the invention, which will enable others skilled in the art to which it appertains to use the same.

The object of the invention is to administer mechanical pulsation vibrating in musical rhythm, with also the attendant harmonics.

Another object is to produce commercially a device by which musical harmonics may be imparted or administered to the human body mechanically without sending electrical pulsations broken up into musical rhythm, as is necessary by the use of my former apparatus, Patent No. 651,777, dated June 12, 1900.

Another object is to construct a device of but few parts easily understood and operated and at such a lowpricc as to enable persons of very moderate means to own and operate the same.

Having stated the object of my invention, I will now describe my apparatus and method of its application, reference being had to the accompanying drawings, in which similarletters indicate similar parts.

Figure 1 is a diagrammatic view of the various parts and connections. a and a are two electromagnetic interrupters commercially known as buzzers. b is a switch adapted to open and close the battery-circuit. I) is a battery or other source of electrical energy,

but preferably a dry battery. 0 and c are the wires forming the part of the circuit. The buzzers a and a are bridged across the circuit in multiple by the contact of the sev-- eral binding-p osts (Z (Z and e e.

Commencing at the electric battery Z), Fig. 1, and follow ing the wire a to the binding-post cl on the vibrator or buzzer a, part of the electric current goes through said buzzer a to the binding-post (Z, returning thence along the wire a through the switchb to the battery I). The

remainder of said electric current continues on the wire 0 to the binding-post c of the buzzer a, thence through said buzzer to the rails or other part of a bedstead, or, when desired, to the inside of a box or other suitable form of an inclosing case.

Fig. 4. shows a cross-section drawing of a box containing my invention arranged in such a manner as to give the greatest amplitude of vibration. The vibrators or buzzers a and a are attached to the containing case or box g by means of a metallic vibratory rod,

(shown at 11 which vibratory rod is attached to the outside inclosing case 9' at the point 13 the said vibrators or buzzers being attached to said rod at the point N.

Fig. 2 shows a plan of attaching my device to a table when it is desired to receive the harmonic vibrations through the hands and feet. The table. g has its upright stem g hollowed out, as at 9 in order to receive the various parts of my device. Z) is the battery. The buzzers a and a are rigidly attached to the interior portion of the table g by the screws f and f. The switch Z) is placed on the outside of the table 9 and connected in circuit with the battery and buzzers on the inside of the table, as shown in Fig. 2. In order to get the mostbenefit from theharmonic vibration when a table is used, the lower part of the table can be fitted with a projecting foot-piece h, made of metal, wood, or other suitable material. In this form of construction several persons can sit around the table at the same time, and by placing their feet at different places on the beveled portion, as at h, of the foot-piece 72-, and at the same time placing their hands on the top of the table, can receive the mechanical harmonions vibrations imparted to the table by the rigidly attached and electrically actuated buzzers vibrating in pairs. Not only are the different fundamental pitches of the two buzzers imparted to the table received by the person in contact therewith, but also the harmonies set up by the lack of perfect accord and tune of the two b uzzers when pitched together and then slightly put out of tune.

In tuning the two buzzers they can be tuned, preferably, in fifths, as one to O and the other to G above, and then slightly lower or flatten either one. I-Iarmonics of a much lower pitch than either of the buzzers will be imparted to the inclosing case containing the various parts of my device when the two buzzers which set up the fundamental tones are rigidly attached to the inclosing case.

The vibrators or buzzers which are attached to the metal rod or tongue at Z), as shown in Fig. 4, may be tuned as follows: After turning the electric current through them, as shown in Figs. 1, 2, 3, the buzzers or vibrators are tuned by turning the adjusting-screw of said buzzers or vibrators with a screw-driver or other instrument until the greatest harmonic eifect is arrived at. In case it should be advisable not to use the Lungen buzzer, but vibratory reeds, then the tuning of said vibratory reeds could be done by filling or otherwise thinning or shortening said reeds until the desired harmony be reached.

The application of my apparatus to practice is as follows: When connected up, as shown and described, and attached to the inclosing ease or bedstead or other box or inclosing case, it is then only necessary to turn on the switch which closes the circuit, causing the battery-current to divide and flow through the two buzzers in multiple. Then the hands or any other portions of the body desired may be placed in contact with the vibrating body to which the buzzers are attached and the persons so in contact therewith will have imparted totheir system mechanically the harmonies and tones set up by the vibrating buzz ers. In regard to the imparting of vibrations to the surface of the inclosing case and subsequently to the human body it will be readily seen from the drawings that a special and new method is used which is decidedly different from the ordinary impartation of the vibrations of a common Rhumkorff coil or other vibrator or buzzer inclosed in a box. By ref erence to Fig. 4 of amended drawings it will readily be seen that the vibrators or buzzers a and a are attached to the end of the vibratory tongue b at b and the vibrations set up by the buzzers or vibrators CI, and ct are conducted through the vibratory tongue b to the point of contact with the outside inclosing case 19 In order to impart said vibration from the outside inclosing case of said box to the human body, the feet, hands, or any other part of the human body are brought into contact with said inclosing case, preferably at the point designated by 12 which is directly over the point of contact of the vibratory tongue b Fig. 3 shows my device connected up in a eigar-box, which form of construction can be made very cheap and adapted to be used by attaching to a bed, held in the hand, or other suitable manner. The similar letters will indicate how it is connected and attached to the box and will enable any one to construct the same.

It is evident that many Variations from the above-described device may be made without departing from the spirit of my invention. In view of this I do not desire to confine myself to the exact description as shown.

Having described my invention and method of applying it, what I claim is 1.

In an electrovibratory therapeutical apparatus, a series of electromagnetic vibrators, adapted to be attuned, in circuit with the battery, said vibrators being attached to an inclosing case, the said inclosing case being adapted to take up the tones and harmonies set up by the electromagnetic vibrators, said inclosing case being also adapted to impart its harmonic vibrations to the human body when in contact therewith.
